| Where does the Slender-billed Curlew nest, and what future does it have? Adam Gretton, Alexander K. Yurlov and Gerard C. Boere |
This paper reviews and includes passages from the only fully documented accounts of nesting Slender-billed Curlews Numenius tenuirostris, by Valentin Ushakov of Tara, southwest Siberia, between 1909 and 1925. It then summarises some of the more recent search efforts, before considering the likelihood of the current nesting grounds being found. Unless greatly increased efforts are made, the species appears to be heading inexorably for extinction

| Evolutionary relationships of stonechats and related species inferred from mitochondrial-DNA sequences and genomic fingerprinting Michael Wink, Hedi Sauer-Giirth and Eberhard Gwinner |
| Sequence data of the mitochondrial cytochrome
b gene and genomic fingerprinting provide good evidence that the geographically
separated taxa of the Common Stonechat Saxicolo torquato complex represent distinct
genetic lineages, which became separated more than one million years ago.The distinct
genetic pattern implies that hybridisation and gene flow between these lineages no longer
takes place to a significant degree. Since these lineages also differ in morphology,
breeding behaviour, vocalisations and physiological control of their annual cycles, we
suggest treating European Stonechat S. torquata, African Stonechat S. [t.]
oxillaris, Reunion Stonechat S. [t.] tectes, Canary Islands Stonechat S.
docotioe and Siberian Stonechat S. [t.] maura as 'good' and distinct
species
